"Hijishime: Part 1" shows Josh Gold sharing the technique with Mark Cheng. During Mark and Josh's training session, Matsuoka Sensei stopped by the dojo to say hello to Mark.
Sensei didn't bring a gi, but unexpectedly got on the mat in his street clothes to share postural and body structure principles related to the technique.
Mark Cheng, Josh Gold, and Nastia Shuba are present during the session.
